Embodiment Construction

[0031] In the following description, the invention is mainly described with reference to a vehicle equipped with a sunshade system, whereby the interior, exterior, innermost, outermost, front, rear and sides are described with respect to the passenger compartment as the interior of the motor vehicle. In the description below, the sun visor and control unit are positioned in the roof of the vehicle, however other locations are also possible.

[0032] figure 1 A perspective view of a vehicle equipped with a sunshade system 1 according to an exemplary embodiment of the present invention is shown. exist figure 1 In , the roof 15 of the carriage can be seen in perspective. The roof 15 is provided with a sun shading system comprising a sunroof or a panoramic sunroof in the form of a sun visor 2 and a control unit 3 . The control unit 3 is not exposed and is therefore shown with dashed lines. figure 2 is along figure 1 Detail cross-section of the visor taken on line II-II.

Abstract

A sunscreen system is provided comprising a control unit and a sunscreen having a first nonplanar glass layer and a nonplanar display layer having a first side and an opposite second side. The first side is adhered to the glass layer, wherein the display layer comprises a plurality of display subareas covering the overall surface of said display layer. Each separate display subarea may be controlled by the control unit to change the subarea's transmittance. The invention is based on the insight that a nonplanar design allows integration in a vehicle body and that a plurality of display subareas allows partial area-wise blocking of light. All electronic components can be provided in or adjacent to the sunscreen or be arranged at another location in the vehicle, leading to a flexible design which for example allows a larger area panoramic roof due to reduction of mechanical components in the roof structure.

Description

technical field [0001] The invention relates to a sunshade for a vehicle and a vehicle with an integrated sunshade for a vehicle window. In particular, the invention relates to sunshade devices with controllable light transmission. Background technique [0002] Current sun protection solutions on vehicle glass mainly include protective covers such as sun visors, side / rear window visors, trunk lids, etc. These covers are typically located in a relatively fixed position inside the vehicle and are manually operated, eg by folding or pulling open to release. Similarly, some current sun protection solutions on sunroof systems include mechanical roller blind systems, often motorized. These roller blind systems usually have several components, such as electric motors, frame systems, drive systems and fabric roller blinds, and these components require a large packaging volume, ie they occupy a large part of the roof interior. In addition, they create weight, cost and quality rela...
